In testing my objects flying over in a mission, far about 500 meters - 1000 meters, the lines begin to flicker.
It may come from a texture, after drawing a softy color skin, solved I think.
And outside of 1000 meters, seen like painted in 1 color white or green, maybe LOD's using Highway_32.tga problem.
Only about Highway_32.tga , painting only gray seems better instead of resizing original Highway_512.tga .
